Why Organizations Choose ATEK Over Vaisala
When Professor Vilho Väisälä invented the radiosonde in 1931, he created a company that would define atmospheric measurement for nearly a century. Today, Vaisala’s viewLinc Continuous Monitoring System is installed in pharmaceutical facilities worldwide — and for many organizations, it is the system they are evaluating replacing. The question is not whether viewLinc works, but whether its enterprise pricing model, European support structure, and legacy on-premises architecture still serve North American regulated facilities as well as a purpose-built cloud-native alternative.
Understanding Vaisala
Vaisala Oyj (VAIAS:HEL) is a publicly traded Finnish technology company founded in 1936, headquartered in Vantaa, Finland. With approximately 2,500 employees and $664 million in trailing twelve-month revenue (as of September 2025), Vaisala operates across two business segments: Weather and Environment (the majority of revenue, covering meteorology, aviation, renewable energy, and air quality) and Industrial Measurements (environmental monitoring, process instrumentation).
Vaisala’s environmental monitoring platform, viewLinc, is available in two deployment models: viewLinc Enterprise Server (on-premises, customer-hosted) and viewLinc Cloud (SaaS, hosted on AWS). Their VaiNet wireless technology uses proprietary LoRa-based RFL100 data loggers connecting through AP10 access points, with each access point supporting up to 32 loggers. In North America, Vaisala operates from Louisville, Colorado (~400 employees), with calibration services coordinated through their Americas Service Center in Boston.
Vaisala’s corporate strategy has recently pivoted toward weather and climate data — their 2024 acquisitions included Speedwell Climate (UK, weather risk), WeatherDesk (from Maxar, weather data), and Quanterra (UK, atmospheric CO2 monitoring). The Industrial Measurements segment, which includes viewLinc, continues to operate but is not the primary growth driver.
Vaisala’s recognized strengths include:
- Global Brand and Scientific Heritage — Nearly 90 years of measurement science expertise, with sensors deployed on Mars rovers (Curiosity, Perseverance). This heritage gives Vaisala unmatched brand recognition among quality managers who have worked with their instruments throughout their careers.
- Comprehensive Parameter Coverage — viewLinc monitors temperature, humidity, dew point, CO2, differential pressure, barometric pressure, and more through a single platform. The Indigo transmitter family allows multiple sensor types on one device with a responsive display.
- viewLinc Cloud and VaiNet Wireless — The newer viewLinc Cloud offering provides continuously validated FDA 21 CFR Part 11 compliance with 7-year data retention, pre-scheduled updates with customer preview instances, and AWS hosting. VaiNet wireless loggers achieve 100+ meter range through concrete and metal barriers using LoRa technology.
Common Challenges with Vaisala
Organizations evaluating or currently using Vaisala’s viewLinc system frequently encounter these considerations:
- On-premises infrastructure overhead — viewLinc Enterprise Server deployments require customer-hosted servers, IT staff for software updates and maintenance, and dedicated Device Host PCs for installations exceeding 20 monitoring devices. Each software update triggers a re-validation cycle managed by the customer’s quality team.
- Proprietary wireless ecosystem — VaiNet uses Vaisala’s proprietary LoRa-based protocol, meaning hardware is exclusively sourced from Vaisala. Each AP10 access point supports a maximum of 32 loggers, requiring additional access points and network planning for larger deployments.
- Quote-based pricing with feature-level licensing — viewLinc pricing involves separate quotes for hardware, software licenses, optional feature add-ons (Voice/SMS alerts, Modbus device support, OPC UA Server, Web API access), support plan tiers, IQOQ validation documentation, and calibration services. The total cost of ownership can be difficult to predict before deployment.
- Support response tied to contract tier — Vaisala’s documented support commitment for contract customers is a response “within one business day.” For facilities where a temperature excursion at 2 AM threatens pharmaceutical product worth hundreds of thousands of dollars, next-business-day is a long time to wait.
- Calibration logistics for Canadian facilities — Vaisala’s nearest ISO 17025-accredited calibration center for North America is in Boston. Canadian facilities face cross-border shipping, customs documentation, and extended turnaround times compared to domestic calibration services.
How ATEK Addresses These Needs
5-Minute Guaranteed Response for Excursion Emergencies: Vaisala’s Americas Service Center coordinates support from Boston during business hours, with contract customers promised a next-business-day response. When a viewLinc alarm fires at 2 AM Eastern because a freezer holding $500,000 in biological samples has drifted out of range, “next business day” means the problem is 8 hours old before anyone acknowledges it. ATEK’s Montreal-based compliance monitoring specialists guarantee a live human response within 5 minutes, 24/7/365 — because excursions don’t follow business hours.
A2LA-Accredited Calibration Without Border Crossings: For the hundreds of Canadian pharmaceutical facilities that currently ship Vaisala sensors to Boston for calibration, ATEK’s in-house A2LA-accredited lab in Canada eliminates international shipping, customs paperwork, brokerage fees, and the 3-4 week turnaround that cross-border logistics create. Calibration certificates, sensor verification, and traceability documentation are handled domestically in a single coordinated process. Learn more about ATEK’s pharmaceutical monitoring platform.
Cloud-Native Architecture Without Legacy Baggage: viewLinc evolved from an on-premises client-server application into a hybrid cloud offering. ATEK’s platform was built cloud-native from the start — no customer-managed servers, no Device Host PCs, no re-validation cycles when software updates deploy. Sensors connect directly to the cloud, dashboards update in real time, and compliance features work out of the box without optional add-on licensing.
All-Inclusive Pricing That Replaces Quote Complexity: Vaisala’s pricing model requires navigating separate quotes for hardware, software licenses, feature-level add-ons, support plans, IQOQ protocols, training, and calibration services. ATEK bundles everything — hardware, software, calibration, validation documentation, unlimited user training, and 24/7 support — into a single per-monitoring-point price. No feature licenses, no support tiers, no surprise line items at renewal.

Who Benefits Most from Switching
- viewLinc Enterprise Server customers approaching license renewal who are evaluating whether to continue investing in on-premises infrastructure and IT overhead, or migrate to a cloud-native platform that eliminates server management and re-validation cycles
- Canadian pharmaceutical facilities currently shipping Vaisala sensors to Boston for calibration and waiting 3-4 weeks for turnaround, who need domestic A2LA-accredited calibration with faster cycles and no customs delays
- Multi-site organizations tired of quote complexity who want predictable monitoring costs without navigating separate pricing for software licenses, feature add-ons, support tiers, validation protocols, and calibration services
Making the Transition
Migrating from Vaisala viewLinc to ATEK Cloud follows a structured approach designed to maintain continuous compliance throughout:
- viewLinc Deployment Mapping — We audit your current viewLinc installation: sensor locations, VaiNet access point layout, alarm configurations, reporting workflows, and integration points with your LIMS, BMS, or SCADA systems. This identifies which monitoring points transition to ATEK and which (if any) remain on viewLinc.
- Parallel Deployment — ATEK wireless sensors install alongside your existing Vaisala probes and RFL100 loggers. Both systems run simultaneously during the qualification period. Your quality team maintains uninterrupted compliance data from both platforms, ensuring zero gaps in your monitoring record.
- Validation with Included Documentation — Complete IQ/OQ/PQ documentation is included — not an optional add-on. Our team has migrated viewLinc customers before and understands the qualification protocols your QA department requires, including mapping viewLinc alarm thresholds to ATEK’s alerting configuration.
- Phased Cutover — Transition by zone, floor, or facility to minimize disruption. ATEK provides 24/7 support during the first 30 days post-migration, with your dedicated compliance specialist available for any configuration adjustments. Schedule a consultation to map the migration for your specific viewLinc deployment.
When Vaisala May Be the Right Fit
Vaisala is appropriate for organizations that need multi-parameter environmental sensing beyond temperature and humidity — CO2, differential pressure, barometric pressure, and dew point through a single platform with the Indigo transmitter family. Facilities that require on-premises data hosting with no cloud dependency will find viewLinc Enterprise Server meets that need where cloud-only platforms cannot. Organizations with a global footprint spanning Europe, Asia, and the Americas may value Vaisala’s international service center network in Boston, Helsinki, Beijing, Tokyo, and Paris. And for teams with existing viewLinc Cloud deployments that are satisfied with their support experience and pricing structure, the switching cost may not be justified.

Frequently Asked Questions
Is ATEK FDA 21 CFR Part 11 compliant like Vaisala viewLinc?
Yes. Both Vaisala viewLinc and ATEK provide FDA 21 CFR Part 11 compliance including electronic signatures, audit trails, and data integrity controls. The difference is implementation: viewLinc Enterprise Server requires customer-managed validation, while viewLinc Cloud and ATEK both offer continuously validated compliance. ATEK includes IQ/OQ/PQ documentation at no additional cost, whereas Vaisala offers IQOQ protocols as an optional add-on.
How long does it take to migrate from Vaisala viewLinc to ATEK?
A typical viewLinc-to-ATEK migration completes in days to weeks depending on the number of monitoring points and integration complexity. ATEK’s wireless sensors install in minutes per location. The parallel deployment phase — where both systems run simultaneously — typically lasts 2-4 weeks to satisfy qualification requirements. This is significantly faster than a viewLinc Enterprise Server deployment, which Vaisala documents as requiring weeks to months depending on infrastructure preparation.
Will I lose my historical viewLinc monitoring data when switching?
No. Your viewLinc historical data remains accessible in your existing viewLinc installation during and after migration. ATEK begins collecting new monitoring data from the moment sensors activate. For regulatory continuity, both data sets are available during the overlap period, and your quality team can reference viewLinc historical records as needed for any lookback analysis.
Can ATEK match Vaisala’s multi-parameter sensor coverage?
Vaisala offers broader parameter coverage through the Indigo transmitter family — CO2, differential pressure, barometric pressure, and dew point in addition to temperature and humidity. ATEK focuses on the parameters most critical to pharmaceutical environmental monitoring: temperature and relative humidity. For facilities that need CO2 or differential pressure monitoring alongside compliance-grade temperature and humidity, ATEK can coexist with specialized sensors while providing the compliance platform, alerting, and support infrastructure.
Does ATEK support VaiNet wireless sensors?
No. VaiNet is Vaisala’s proprietary wireless protocol. ATEK uses industry-standard WiFi, LoRaWAN, and LTE connectivity, which means your monitoring infrastructure is not locked into a single vendor’s hardware ecosystem. During migration, ATEK sensors deploy alongside VaiNet loggers — there is no need to remove Vaisala hardware until you are ready.
Is ATEK’s pricing actually lower than Vaisala’s?
ATEK’s all-inclusive model bundles hardware, software, calibration, validation, training, and 24/7 support into a single per-monitoring-point price. Vaisala’s total cost depends on your specific configuration: hardware selection, software license scope, feature add-ons, support tier, IQOQ documentation, and calibration services. For many organizations, ATEK’s bundled pricing results in a lower total cost of ownership, but the real advantage is predictability — you know exactly what you will pay before signing, without navigating multiple quote processes.
